(1) A traffic control device (except a road marking) applies to an area if—
(a) it is in the area; and
(b) the device, the position of the device, or information on or with the device, indicates that the device applies to the area.
(2) A traffic control device (except a road marking) also applies to an area if—
(a) there is an identical kind of traffic control device (the first traffic control device ) on each road into the area; and
(b) the traffic control device is a traffic control device applying to an area, or information on or with the device indicates that it applies to an area; and
(c) information on or with a traffic control device on each road out of the area indicates that the first traffic control device no longer applies or that the area has ended.

(5) A parking control sign that applies to an area applies to parking bays on each length of road in the area, and to other parts of each length of road, as if it were a parking control sign that applied only to that length of road.
